Using a class that has a main from another class

Question

Can I call a class that has a main from another classes public methods?

Answer 1

Yes, you can, although strictly speaking you won't be calling that classes "main" method, you will simply be calling and initializing the class through it's constructor, the "main" method will be ignored. If you have code inside your main method that you want executed as well consider moving it inside your constructor and simply using the "main" method as an application initializer:
public static void main( String args[] ) {
new MyClass();
This way you can use your class as an application or call it from another class and not have any duplicate code inside your "main" method and constructor. You can also take this further and have it call the applet initialization so that you can launch it any way you like, I suspect this is a bit beyond what you were asking.
Does this solve your problem?
